Abstract
Abstract An absorbent article is disclosed for absorbing and retaining human exudate. The article includes an absorbent having a first surface facing the body of a user and a second surface aligned approximately opposite to the first surface. A liquid-impermeable baffle is positioned adjacent to at least the second surface of the absorbent while a fluid permeable cover is positioned adjacent to at least the first surface of the absorbent. A deodorizing mixture is positioned within the article and is positioned to remain dry for a substantial period of time. The mixture is an anhydrous, non-buffer blend of acidic, basic and pH neutral odor absorbing particles.
